Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is thigmotropism?
A
A plant’s response to water near it
B
A plant’s response to gravity
C
A plant’s response to light near it
D
A plant’s response to touch
Explanation: 

Detailed explanation-1: -In plant biology, thigmotropism is a directional growth movement which occurs as a mechanosensory response to a touch stimulus. Thigmotropism is typically found in twining plants and tendrils, however plant biologists have also found thigmotropic responses in flowering plants and fungi.

Detailed explanation-2: -Thigmotropism is when plants grow in response to touch or contact with objects. For example, vines have small tendrils that curl around walls or trellises.

Detailed explanation-3: -Thigmotropism can be defined as the movement of a plant part in response to touch. It can also be defined as the curvature movement of plant parts like tendrils in response to the stimulus of contact or friction with some other object.

Detailed explanation-4: -Thigmotropism. The growing or developing movements made through plants in response to contact with a solid object are called thigmotropism. These type of movements are usually seen in tendrils and twiners. This movement is also referred to as Haptotropism.
